My husband and I were traveling to charleston, sc on I-26 to have a nice valentine's weekend. Everything was fine until we merged onto I-26 in columbia, sc, when we felt a small jolt in the truck like it was hesitating or something. So we dismissed it as maybe bad gas or something. It happened a couple more times and as we were passing a rest area outside of orangeburg, sc in the left lane going with the flow of traffic at about 80 MPH, the whole truck just shut down. No power steering and the car will not crank in neutral. Traffic is pretty heavy on a holiday weekend, and I have tractor trailer beside me and behind me on a two lane interstate. Trying not to panic, I put on the hazard lights and waving out the window like crazy trying to get these truck driver's attention, thank god they noticed and the one beside me sped up and my husband was able to get over by the exit of the rest area. After thanking god for our lives, we decided to try and make it to a dealership in orangeburg. We get there, and after 2 hours they say it was the throttle body and a tune up $300 bucks and another 2 hours we finally got on our way. We made it to charleston and salvaged a pretty good day trip considering what we went through, with no problems. It jolted once on the way back about 40 miles from home. So the next day I remembered we had gotten a letter from chrysler, and when we looked at it we realized that the recall was the real problem. This letter came in september of 2013, and we have not heard anything from them since then, almost 2 years later. Also, you would think that a jeep dealer would know about recalls on all of the vehicles they sell when they put the VIN in the system. Now we just use the one key, stay close to the right lane and hope for the best. Another car/payments is not an option.

Purchased 2007 jeep grand cherokee overland 5.7 on 11/30/2012. On 12/04/2012 I experienced stalling while decelerating to stop for a stop light, then the vehicle stalled showing code p0884. The vehicle started right back up when I turned the key with no signs of hesitation. Ever since that day, my vehicle stalls on average about 8-10 times per week depending on how often I use the vehicle. It stalls mainly during idle or coming to a stop and the most frightening stall I have experienced was when I was traveling at 60mph on a major highway and the vehicle completely stalled, and instantly restarted itself. Both times I experienced stalling at high speed was when I was doing about 60mph and both times the vehicle restarted itself on its own. But every time the vehicle stalls, I loose all power including power steering which worries me very much. Apparently I am not the only 2007 jeep grand cherokee overland with the 5.7 motor owner experiencing this problem. I am one of the hundreds on owners involved in a group discussion on jeepforum.com where we discuss this problem and steps that jeep, private mechanics, and/or owners themselves have taken to correct this stalling problem. This problem has been going on for years and no one seems to have a solution. Loss of power at 60mph is a very big issue and I worry that someone can be very hurt or killed by loss of power steering during stalling. I hope this issue raises concerns for my vehicle and I would be more than willing to allow someone from the federal safety agency come and test drive my vehicle to experience what I and hundreds, possibly thousands of others are experiencing. Thank you very much and if you should have any questions in regards to this problem, please do not hesitate to contact me any time.

My jeep will just shut off while driving. It is not soon after starting so the engine is not cool. It has happened on the interstate twice without warning. There is not hesitation or sputtering, you just feel you are decelerating and then you realize you have no acceleration or power steering or brakes. I was in the far left lane and extremely worried I would not be able to safely make it over to the shoulder. Other times it has happened on secondary roads and I have had to park it and then restart it in the middle of the road. When it starts and I put it into drive, it will not engage into gear. I have taken it to the dealer three times and they cannot find the cause but checked all sensors, transmission, changed spark plugs, PCM, and updated the computer. It happened again this weekend except it lurched first then shut off. I got online and see that many others have reported the same problems so I felt I needed to report it in the event this truly is a more widespread problem. Thank you.

I purchased this vehicle on december 14, 2011. About three weeks later in a parking lot, we noticed the vehicle would not accelerate even though the accelerator pedal was pushed virtually all the way down. A few days later the engine warning light came on. Then the lack of acceleration happened on the interstate. My mechanic cleared the engine warning light but it came back on a few days later. I did a lot of research and it appears this is a common problem on jeep vehicles. The problem is a failure of the electronic shift module. It if very expensive to have replaced. My local dealership charged me $924 plus tax. As many comments as I have seen on this and the fact that lack of acceleration is a safety issue, jeep should not hesitate in issuing a recall.

Upon acceleration from stop vehicle will hesitate and lose power. This constitutes a hazard to vehicle and any approaching vehicles during a turn. Inspection indicates that transmission electronic control module is at fault along with a possible transmission sensor failure. The check engine light will come on. Both of these conditions ( power and check engine ) are intermittent, indicating that the module is faulty. There have been many complaints about the transmission ECM on these vehicles. The other complaints have varying symptoms but all go back to the transmission ECM. These unit should be recalled and repaired or replaced at manufacturers cost. This problem exists in many different models and years of vehicles, but always go back to this ECM unit. After investigating this problem I don't feel that the consumer is at fault or causing this to occur. Chrysler modules are and have been faulty in the past. Anecdotal evidence says that other modules in chrysler vehicles have had problems too. Please investigate the chrysler transmission ECM's and have them recalled.
